The mare seemed to know that something unusual was afoot. Perhaps some nervous tensity of her rider made itself felt, perhaps with equine sagacity she had understood from the first the nature of this scouting expedition. Dave was inclined to believe the latter--he had often averred that Bessie Belle knew quite as much as or more than he. At any rate she picked her way with admirable care, her hoofs made almost no sound upon the wet soil; only the complaint of the saddle leathers or the swish of a wet branch rose above the steady patter of the raindrops. It was not necessary to guide her; she selected the openings of her own free will, her small, sharp ears were alert, and her eyes searched the glades intently. Dave smiled at this excess of caution and stroked Bessie Belle's wet neck encouragingly, whereupon she turned her head and it seemed to the rider that she nodded her complete understanding. Law could have kissed her. X A RANGER'S HORSE Onward through the dense foliage the two friends wound. Now and then they stopped to listen, but the rain was heavy enough to drown all other noises. Encountering fresh tracks finally, Dave leaned from his saddle and studied them. What he saw caused him to push forward with no diminution of stealth. He had gone perhaps half a mile when Bessie Belle raised her head, and he noted that her nostrils were working sensitively. A few yards farther on Law fancied that he could detect the smell of a wood fire. Almost without a signal from him the mare halted in her tracks until he had satisfied himself. Still farther along they came to a place where the brush was low, and there, rising through the tree-tops beyond, they saw a wavering plume of blue smoke.
